The invention provides an aluminum-titanium diboride-phosphorus master alloy and a preparation method thereof, which comprises aluminum element, titanium element, phosphorus element and boron element, and the mass percentages of each component are: titanium element 1.4-5.8%, phosphorus The element is 2.0‑6.0%, the boron element is 0.7‑2.8%, and the rest is aluminum element. The aluminum-titanium diboride-phosphorus master alloy of the technical solution of the present invention is used as a high-efficiency primary silicon modifier, which can significantly refine the silicon phase in the eutectic and hypereutectic aluminum-silicon alloys and effectively improve the comprehensive mechanical properties of the alloys. , the preparation method of the aluminum-titanium diboride-phosphorus master alloy provided by the invention is convenient to operate, low in price, and suitable for large-scale production. |
